Shannon Cornell Johnson was 29 when he was killed by gunfire in Knoxville, Tennessee, on May 8, 2004. The case is officially an unsolved homicide: investigators determined the cause of death was gun violence, but no arrests have been announced and no suspects have been publicly identified.

The Knoxville Police Department continues to list the death among its cold cases. Family and friends have lived with years of unanswered questions and the absence of closure, while the investigation remains open pending new information.

Does anyone who lived in Knoxville in 2004 or who may have been in the area on or around May 8 have information that could help this case?
